You can submit an erratum and an author will comment and often clarify, so formally speaking the answer to your question is yes. But other implementers don't generally read the errata, so you have to expect that your interoperation peers haven't read the clarification.

Once you understand the problem, the clarification, and that your interop peers do not, I bet your implementation's handling of the issue will be conservative in what it sends and liberal in what it receives.
